Weird behavior on eventEndSpec set to "Date"

This issue should be fixed now in the latest sandbox build (2021.1.4831):

https://javascript.daypilot.org/sandbox/

Please let me know if the problem persists.

It's fixed in that build (trial) on resize feature, but when I use simple dateRange selecting for create new event, forward drag is fine, but back drag is in pairs, same bug like main question but in opposite side and on dateRange select.

The last release pro version available that I have is (2021.1.4828), how often do you upload a new releases?.

Thank you!

There was a small problem with excessive onTimeRangeSelecting invocation when eventEndSpec is set to "Date" but other than that it seems to work fine. Could you please give it a try with version 2021.1.4832?

If you still see the problem, can you please post a config that reproduces the issue?

Ok it's fixed, thank you so much for your support.
